The product formed in the reaction is –
In the above sequence of reaction X and Y are respectively
KMnO4converts – CH3 group of toluene into – COOH while HI reduces – COOH group into – CH3 group.
Monocarboxylic acids are functional isomers of :
Mono-carboxylic acids are functional isomers of esters.
How many cross aldol products (without counting stereoisomers) are produced in the following reaction?
The correct order of increasing acid strength of the compounds
is
The correct order of increasing acid strength
CF3. COOH > MeOCH2COOH >CH3COOH> (Me)2CH.COOH
Electron withdrawing groups increase the acid strength and electron donating groups decrease the acid strength.
Reaction of butanone with methyl magnesium bromide followed by hydrolysis gives
The increasing order of the rate of HCN addition to compound A – D is
(A)HCHO (B)CH3COCH3
(C)PhCOCH3 (D)PhCOPh
Addition of HCN to carbonyl compounds is nucleophilic addition reaction. The order of reactivity of carbonyl compounds is Aldehydes (smaller to higher)Ketones (smaller to higher),Then
HCHO > CH3COCH3 Ph.COCH3 PhCOPh
The lower reactivity of Ketones is due to presence of two alkyl group which shows +I effect. The reactivity of Ketones decreases as the size of alkyl group increases.
Reaction of cyclohexanone with dimethylamine in the presence of catalytic amount of an acid forms a compound if water during the reaction is continuously removed. The compound formed is generally known as
Which compound among the following gives positive iodoform test ?
1.Ethanol 2.Ethanal
3.1-Butanol 4.2-Butanol
5.Phenyl ethanol
Polarization of electrons in acrolein may be written as:
